Overview of Comcast Business

Part of the larger Comcast corporation founded in 1963, Comcast Business is a major telecommunications provider headquartered in Philadelphia, Pennsylvania. The company is a significant force in the industry, ranking 33rd on the Fortune 500 list with about 190,000 employees.

Operating primarily in the United States, Comcast Business provides connectivity solutions for organizations of all sizes. They are known for offerings like long-term price guarantees and security features that are integrated directly into their network connection, which can simplify security management for businesses.

Overview of Frontier Communications

Frontier Communications has a long history, with corporate roots tracing back to 1935. Headquartered in Dallas, Texas, the company operates with around 13,000 employees and provides services across 25 states in the United States.

Frontier Communications is known for its extensive 100% fiber-optic network, which delivers symmetrical speeds and maintains 99.9% overall network reliability. The company focuses on providing business-grade internet without premium costs and offers flexible month-to-month billing for its small business fiber plans, avoiding long-term contracts.

ISP Products

Dedicated Internet (DIA)

Comcast’s Ethernet Dedicated Internet (EDI) and Frontier’s Dedicated Internet Access both provide symmetrical speeds up to 100 Gbps over fiber. Both services come with a 99.99% uptime SLA, and Frontier specifies a four-hour mean time to repair for its managed DIA product. While Frontier delivers its service exclusively via fiber, Comcast offers more transport flexibility, using fiber, coax, or a hybrid fiber-coax connection.

According to Lightyear's data, Frontier's average DIA installation timeline of 77 days matches the market average, while Comcast's is slightly longer at 82 days. For pricing on a 100 Mbps circuit, both are competitive, with Comcast and Frontier coming in 15% and 12% below the market average, respectively. On a 1 Gbps circuit, Frontier is about 11% more affordable than average, while Comcast’s pricing is on par with the market.

Both providers offer common add-ons like managed routers and security services. A key operational difference is the physical point of delivery; Comcast can bring the connection directly into a customer's suite, whereas Frontier typically terminates service at the building's main point of entry (MPOE).

Please note that these are aggregate figures; timing and pricing can vary significantly based on your region and specific DIA configuration.

DIA Pricing, Delivery and Install Days Compared

The data in this table comes from Lightyear’s aggregated ISP quotes collected in 2024 and 2025 YTD.

• Install Days: how long it typically takes to deliver service.
• 100Mb Price vs Avg / 1Gb Price vs Avg: shows whether this ISP is cheaper or more expensive than the market average.
• Delivery Point: “Suite” means the ISP delivers service all the way to the company’s server room; “MPOE” means the circuit stops at the building’s minimum point of entry (typically the building's utility basement) and the tenant must handle the inside wiring.

Wireless

Comcast Business and Frontier approach wireless services from fundamentally different angles. Through its Xfinity Mobile brand, Comcast provides mobile plans for phones and personal devices, running on Verizon's 5G network and supplemented by a vast system of WiFi hotspots. This makes it a direct option for companies looking to manage their mobile device connectivity.

In contrast, Frontier focuses on business continuity rather than individual mobile plans. The company offers a managed cellular failover service that acts as a backup internet connection for business locations. This service, part of their managed network offerings, automatically activates if your primary connection fails, ensuring your operations stay online.

Security

Comcast Business offers security products tailored to different business sizes. Its SecurityEdge service provides a foundational layer of defense against cyberattacks for most business customers. For larger organizations, Comcast provides a suite of Managed Security services, including managed firewalls, Unified Threat Management (UTM), secure VPNs, and DDoS protection for its Ethernet products.

Frontier Communications, on the other hand, integrates its security offerings directly with its Managed Dedicated Internet service. Customers can add Basic or Advanced security bundles that include features like a firewall, UTM, remote user VPN, and web filtering. A key component of Frontier's approach is the inclusion of 24/7 monitoring and management with these security services.

Broadband

Comcast Business Internet runs on a hybrid fiber-coax network, delivering asymmetrical speeds with downloads up to 1.25 Gbps and uploads capped at 35 Mbps. This service includes a 1.2 TB monthly data cap. According to Lightyear's data, Comcast's broadband pricing is about 33% higher than the market average, and installation takes around 31 days, slightly longer than the 28-day average.

Frontier’s Business Fiber, by contrast, uses a 100% fiber network to provide symmetrical speeds, with some markets offering up to 7 Gbps. A key benefit is its unlimited data policy, meaning businesses don't have to worry about utilization caps.

Due to limited quoting history for Frontier's business broadband, we’re not able to provide benchmark pricing or installation timelines at this time. You can get the most current pricing for your specific location by filling out our questionnaire to receive a real-time quote.

Ethernet

Frontier Communications offers MEF-compliant Carrier Ethernet, including Ethernet Private Line (EPL) and Ethernet Virtual Private Line (EVPL). These services are built for businesses that need to establish a private, secure network between multiple locations, with optical transport speeds available up to 100 Gbps.

Comcast Business provides a similar portfolio of Ethernet network services for creating wide area networks (WANs). A key difference lies in the delivery method; while Frontier uses its all-fiber network, Comcast can deliver Ethernet services over fiber, coax, or a hybrid fiber-coax connection, offering more flexibility in areas served by different infrastructure.

POTS Replacement

Comcast’s Business Voice and Frontier’s POTS Connect both offer modern replacements for traditional analog phone lines used for specialty applications like alarms, faxes, and point-of-sale systems. A key difference in their approach is that Comcast’s service is closely tied to its internet offering, while Frontier’s solution is designed to operate over LTE or a wired backhaul.

For businesses with critical safety systems, Comcast notes that its voice service aligns with NFPA 72 code for fire alarms and includes a 5-hour battery backup. Frontier’s POTS Connect comes with built-in LTE failover, though details on battery backup and specific code compliance are not publicly listed. This highlights a key operational choice: Comcast’s voice product is most cost-effective when bundled with their internet, as using it without can incur additional fees, whereas Frontier’s is a more self-contained solution with its own connectivity.

Other Key Features Compared

Geographic Coverage

Comcast Business focuses its services entirely within the United States.

While they don't operate internationally, their network is extensive across the country, reaching businesses in many different states.

Frontier Communications also concentrates its network within the United States.

The company provides services to businesses in 25 states, with a strong presence in areas where they have built out their fiber infrastructure.

SLA

Both Comcast Business and Frontier Communications offer a 99.99% uptime Service Level Agreement (SLA) for their dedicated internet products. This is a formal promise from the provider about the reliability of your connection.

In practical terms, a 99.99% uptime guarantee means your service should not be down for more than about 53 minutes over an entire year. It’s a standard for high-availability business circuits.

If the provider fails to meet this uptime promise, they are typically required to give you a credit on your bill. This provides a financial safeguard for service interruptions.

Transport Types Available

Comcast Business uses a hybrid fiber-coax network that spans 200,000 fiber route miles. This infrastructure generally delivers asymmetrical speeds, where downloads are much faster than uploads.

Frontier Communications, in contrast, operates a 100% fiber-optic network across its 180,000 route miles. This allows the company to offer symmetrical speeds, meaning your upload and download speeds are the same.

While Comcast’s speeds are suitable for general business use, Frontier’s symmetrical connection is better for upload-heavy tasks like video conferencing or sending large files to the cloud.

Customer Support

When it comes to getting help, both Comcast Business and Frontier Communications have support teams for their business clients. You can typically reach them through standard channels like phone and online portals.

As a larger company, Comcast has an extensive support network. They provide specialized assistance for their different products, from basic internet to managed security services.

Frontier also offers dedicated business support. For certain managed products, they include 24/7 monitoring, which means their team is always keeping an eye on your connection's health.

Final Verdict: Comcast Business or Frontier Communications?

The choice between Comcast Business and Frontier depends on your company's specific needs and location. Their primary difference is network type: Comcast uses a flexible hybrid fiber-coax system, while Frontier operates a 100% fiber-optic network.

Comcast is often a good fit for businesses needing broad service availability where fiber isn't present, as they can deliver service over coax. Their asymmetrical speeds are suitable for general web use, and they offer service bundles that include mobile plans.

Frontier, in contrast, is ideal for businesses needing high upload performance for video calls or cloud backups. Its all-fiber network provides symmetrical speeds and unlimited data, a key advantage for data-heavy work.

Ultimately, the right provider depends on availability and pricing at your specific location. We recommend getting a real-time quote to compare your exact options from both providers.
